Any disease caused by bacteria. Bacteria exist in a variety of relationships with the human body. They colonize body surfaces and provide benefits, e.g., by limiting the growth of pathogens and by producing vitamins for absorption (in a symbiotic relationship). Bacteria can coexist with the human body without producing harmful or beneficial effects (in a commensal relationship). Bacteria may also invade tissues, damage cells, trigger systemic inflammatory responses, and release toxins (in a pathogenic or infectious relationship).
